PROBLEM TO BE SOLVED: To provide a communication terminal device which can prevent a line from being released, even if a hook key is operated when the line is forcibly closed. SOLUTION: When a recording part 50 is unable to operate, an image memory 80 is exceeded memory, and the telephone line L is closed with a line closing key 69. At those settings, the telephone line L is closed to disable facsimile reception. In this state, the operation of the hook key 66 is invalidated. Consequently, the telephone line L will not be released, even if the hook key 66 is operated. Therefore, when the telephone line L is forcibly closed, the telephone line L can be prevented from being released, even if the hook key 66 is operated.
